3 SNPs were nominally significant with the most statistically significant difference observed for rs514659 in the ABO gene determining the ABO blood group (frequency of the minor allele C in STEMI patients 48.06% and in NSTEMI patients 43.26%; X2 P = 0.0066), originally reported to be specifically associated with MI in presence of CAD [20]. This evidence concerns the gene ABO and coronary artery disorder.
